Just opened the iMac 27 up and saw this on the corner, its a very little etch, wanted to get opinion if anyone else noticed this on their iMac?
Should I replace or keep using it.
It is a nice computer though.

Of course I would want it unmarked but I wouldn't be too sad about what your photo shows. In fact it will make it more unique so if ever on some strange event there is an iMac party where about 500 iMacs get loose over night and you have to go pick it up because she/he had too many dvds you will easily be able to tell which one is yours while they are all snoozing.

I think it's a good thing you called and let them know about the damage. Apple CS keeps records of all this and even if this damage looks insignificant it may be an endemic problem coming from a particular factory/assembly team.
Without feedback like this they cannot improve production. It's worth a $150 for them to have this info.

I am glad they gave you something back. If you pay that much money for something .. it better be perfect.

This is probably part of the reason *why* we pay so much for these Apple goods. I've never seen someone open their Dell and inspect it the way people pour over their Apple products looking for the tiniest flaw so they can return it for a new one.
